RF Switches
RF Switches are electronic components used to provide routing functionality for RF signals. To make the routing of RF signals more efficient, many different types of RF Switches have been developed to improve signal routing performance. In this article, we will discuss SKY13521-001 application field and working principle.
Applications
SKY13521-001 RF Switch is an antenna switch which integrates an RF switch and power amplifier in a single IC package. It is designed to allow multiple radio frequency (RF) antennas to be connected to one single antenna port and act as an antenna multiplexer by switching between one of the antennas. This makes the antenna switch extremely suitable for applications such as dual-band Wi-Fi systems, dual-SIM phones, dual antennas for LTE devices, and so on. In addition to antenna switching, the SKY13521-001 is also used in applications where antenna selection is needed for better signal and noise performance.
Working Principle
The SKY13521-001 is implemented with a CMOS process in which an NMOS and a PMOS transistor are connected as an SHP (Single-ended Half-push) switch. This type of switch arrangement can provide great accuracy and linearity while providing a low switching time. In the SKY13521-001, the switch is controlled by a built-in power amplifier which controls the signal’s output power level. In addition, the device also features an integrated VGA and LNA, which provides excellent gain control and power efficiency. The SKY13521-001 has a single control pin which is used to change the antenna selection. The control voltage level of the pin is determined in accordance with the voltage-controlled gain-block in the device. By varying the voltage level, the user can select either one of the antennas or a combination of antennas, depending on the desired output power level. The SKY13521-001 also features a power-on reset feature which ensures that a reliable RF signal is always available at the device’s outputs.
Conclusion
In conclusion, SKY13521-001 is an ideal switch for applications requiring multiple antenna selection and power control. The device’s small size and integrated components improve RF signal quality and reduce power losses, making it an ideal choice for applications requiring fast switch times and low power consumption. With its high linearity and low switching time, the SKY13521-001 is the ideal choice for applications requiring antenna selection and power control.
